Hei

Jeg ser at det selges tesla coil høyttalere gjennom flere kinesiske nettfirmaer.

Er det noen som har kjennskap til disse produktene?
Brukbare som diskantenhet i et aktivt høyttalersystem med aktiv deling for eksempel?
Genererer slike diskanter ozon slik som de gjorde i tidligere utgaver med gasstank?
Tanker om lydkvalitet?

Hodetelefoner etter samme prinsipp høres ihvertfall ut som en morsom ide.

Og man må ikke glemme Hill Plasmatronics.
Bolse Solheim hadde disse, heftig:)

Var på Munchen high end messa. Min favirittlyd kom fra Acapella. Dem hadde en vektløs diskant utenom det vanlige. 10 av 10 i mine ører. Det var et lite blått lys i disse diskantene. Har dette noe med Plasmaprinsippet å gjøre?

Fikk med med dette: "he Acapella entire treble range is stunning from the ION Plasma."

Fikk meg en opplevelse jeg ikke kommer til å glemme.

Hadde jeg hatt det ungdomligge pågangsmot som for 40 år siden og med tilgang til (søk)
DIY plasmaspeaker ville jeg godt for en slik løsning.

As Nelson Pass said of his massless “ion-cloud loudspeaker” described in the sidebar “[the speaker] gave new meaning to the word ‘transparency.’”

It’s the kind of sound that produces a “fool-you” realism of timbre, as well as “fool-you” palpability and immediacy. There was an ethereal character to the sound, as though the music existed independently of any electro-mechanical contrivance—“conjured out of thin air”

These qualities were nothing short of magical on female vocals

I min verden skyldes det negative i testen ikke høyttalerne,men andre omstendigheter.

perhaps because the tweeters are AC-powered, the system always sounded cleaner at night than it did during the day, when the AC line would be noisier.


(Search YouTube for "singing flame" and you'll find many examples.) This principle was developed into a practical loudspeaker in 1946 by a French inventor, Siegfried Klein

Klein licensed his technology to several companies in the 1950s, including DuKane in the US, which had an agreement in 1958 with Electro-Voice to market the driver as the Ionovac. In 1965 the British company Fane produced a version of the Ionovac, the IonoFane, which I heard just once, used as the tweeter of a B&W P2 loudspeaker.

Siegfried Klein went on to develop the Magnat ionic speaker, which operates on a somewhat different principle. However, another German company, Ingenieurbüro Lansche (renamed Lansche Audio in 2003), was founded in 1998 by Rüdiger Lansche to manufacture a plasma tweeter descended from the Ionophone/Ionovac/IonoFane. This ionic tweeter was developed by Otto Braun, the erstwhile German distributor for the IonoFane and was originally sold as a complete package—including horn, RF generator, class-A amplifier, and power supply—to the DIY market, then to German manufacturer Acapella, which used it in the High Violoncello II loudspeaker, reviewed by me in September 2010.

In 2008 Lansche Audio developed a revised tweeter, the Corona, which they are not making available to other companies.

Selve kromtappen, vektløs ionediskant. "I love the smell of ozone in the morning". Drevet
av en rørbasert klasse A forsterker

For those whose memories of ionic tweeters from other companies were colored by the unmistakable smell of ozone: I could detect no trace of that destructive gas coming from the brass horn
